The boy's wheelchair was stolen this week after his mother left it in the lobby of their building as usual. It is easier for her to carry her son, Joshua Romero, to their second-floor apartment on Merrimac Drive in Langley Park.

Prince George's County police released surveillance video on Thursday showing a person pushing the empty chair in a parking lot and asked for the public's help in identifying the person.

"It's disturbing to have actually seen that happen. We have watched that video. He doesn't look uncomfortable about anything that he did, and that doesn't sit well with me and hopefully it doesn't sit well with members of the community and they reach out to us," Prince George's County police Capt. Ken Humbel said.

On Friday, Nikisha Marshall, of Upper Marlboro, contacted police and said she would donate a customized wheelchair her son outgrew to Joshua. Police have received other offers of donations from as far away as Florida.

Workers at an Anne Arundel County adult day care said they were touched when they heard about the story and decided to lend a helping hand by collecting a few hundred dollars for the Romero family.

"I can't believe that would happen," said Steven Jones, with Foundations Medical Adult Day Care in Linthicum Heights.

Jones said it's about paying it forward.

"If we didn't do it, somebody else would have and hopefully people will continue to help, whether it's helping that family or another family," Jones said.

Workers also said they want to invite the family to visit the National Aquarium in Baltimore.

Anyone with information about the theft is asked to call police at 866-411-TIPS.
